Project Priority Area – J12L

Summary: Project Specifications & Features 1. Addresses ELU (QP water use) and not current use or unlawful water uses . 2. The project identifies users with or without registered use entitlements , whether claims for registered uses are correct, under-estimated, over-estimated or false 3. 2737 WARMS registered users in 3 Primary, 14 Tertiary and 68 Quaternary Catchments. 4. Expect another 30% unregistered users . Quaternary J12L is a priority catchment – Ministerial instruction arising from court 5. actions between users. Complete determinations end-March 2018. Currently in the verification phase. 6. V&V projects are multi-disciplinary / multi-faceted and have very high project management and coordination requirements – internally and externally. 7. User engagement (minimises ELU determination disputes) and BGCMA involvement (post-project continuity) are critical success factors . 8. Where an ELU has not been confirmed, the use becomes unlawful (s35(5)).

Managing Expectations Project Team expectation – everything goes as planned. There are many project 1. variables (internal and external) so planning is for a robust design that incorporates flexibility in approach . User expectation – ELU engagements take place and determinations are available 2. immediately or shortly after project commencement. Generally – the elapsed time period creates several issues (e.g. property ownership 3. and water user changes; uncertainty over extent of WU in the QP; missing / outdated information). Approach to mitigate : engage with users & property owners; work on confidence limits regarding determinations. 4. ELU determinations are NOT absolute and are approximations guided by evidence (visual or documentary) and legal principles.

Methodology – Summary • The process includes identifying land and non-land based water uses (industrial, mining Dr Abel Ramoelo & Team and bulk potable water supplies, irrigation, crop types and impoundments) using remote sensing (RS) techniques for the qualifying period. • Crop irrigation requirements are estimated using the South African Procedure for Dr Evison Kapangaziwiri & Dr Seb Dzikiti estimating irrigation WATer requirements (SAPWAT) , version 4. • The Gush Curves are used to quantify Stream Flow Reduction Activities (SFRAs) - Dr Mark Gush commercially afforested areas, converting areas to volume. • The boundaries of farm reservoirs are delineated from RS and the volumes calculated Dr Jean-Marc Mwenge Kahinda using a regression approach . • Estimates of the irrigation water requirements, SFRAs and reservoir volumes form the basis for interaction between the project team and water users to confirm their uses ; Project Office Staff and subsequently, to update the Water Authorisation and Registration Management System (WARMS), a database of water users.

How is Water Use Validated? – Satellite and Aerial imagery (specific dates & multi-seasons) – Property & Ownership data – WARMS Registration data – Property and Field Surveys – Water User Interaction – SAPWAT Model: Crop Water Use determinations – Dam Volumes : surface area to volume calculations – Stream Flow Reduction Activity : area to volume determinations – Acknowledge local conditions/practices
